The dash board is powered from a "regular" 12-volt car battery. That battery is recharged from the main High Voltage (HV) battery when you first turn the car on, but the 12v has to have enough to get the car's computer systems to "boot" before that can happen. If your dash lights stayed on, that probably drained your 12v battery too far. You can jump the Fisker to get it started, and then drive it around for 15-20 minutes to get the HV interlock to recharge the 12v battery (assuming that it hasn't gone bad and will hold a charge). There's a video here on how to do this:
That may get you going again. But, the real question will be why your dash lights stayed on. Were you out driving in the rain? It sounds like it's possible your VCM (a computer module located in the dash board above the driver's left foot) might have gotten moist. That happened to me, once. The "fix" for it for me was to do a hard reset (which is unplugging the black, main 12v power cable connector inside the hood along the right hand fender wall for 30 seconds). That kinda "resets" everything like powering off your PC. If your VCM wasn't permanently damaged by water, you can go on with life.
There is a Karma factory bug that lets water into the electronics under the dash through the holes where wires go in through the firewall underneath the black plastic air filter ducting system at the base of your windshield. There is an essential fix that should be done to all Karmas to add silicone to those holes and waterproof them. You should try to find out if that was done to your car (or have a CSP just do it). Also the rubber seal at the base of your windshield may be working loose (you can see it coming away from your windshield at places if it is), and may need to be glued back down to seal the water out.
Also, BTW - shortly Karma Automotive will be releasing a new software version for our cars (version 530) that will keep the 12 volt battery from ever getting low so long as the HV battery has power. But, for now, it's important to not let the car sit long enough to let the 12v system get too low. (Or, to let a malfunction drain its power). It could make it so you can't even open the doors.
